Detailed Description of Business Cenforce 120 is a medication used to treat erectile dysfunction (ED) in men. It contains Sildenafil Citrate as its active ingredient, the same substance found in Viagra, but at a slightly higher dose of 120 mg. Sildenafil is a PDE5 inhibitor, which works by relaxing the blood vessels in the penis, increasing blood flow, and helping men achieve and sustain an erection when sexually aroused. By inhibiting PDE5, Sildenafil allows cGMP to accumulate, leading to improved blood flow and an erection. However, sexual stimulation is still required for Cenforce 120 to work effectively—it will not cause an erection on its own.
